Notamia. ZOOPHYTA. CELLARIADyE. 541 



the joints are black, and the tubular radicles are annulated with the same 

 colour. 



Gen. LX. NOTAMIA. — Cells in pairs, united by the back, 

 a joint above and below. — Loricaria, the term employed 

 by M. Lamouroux to designate this genus, having long 

 been pre-occupied in ichthyology, I have substituted No- 

 tamia, — vuToi, deorswn, and ra^jov, cella. 



158. N. loriculata. — Cells subcylindrical and obliquely trun- 

 cated. 



Coat of mail Coralline, Ellis, Cor. 40. t. xxi — Sertularia cor. Linn. Sysl. 



i. 314 Cellularia lor. Pall. El. 64 — Loricaria europrea, Lamour. Zooph. 



7 — Common a few fathoms beyond low water-mark. 



Height several inches, dichotomously branched, fastigiated ; the cells are 

 but little prominent, and, as Ellis has well observed, " the opening of each 

 is on a slant near the top, and looks the contrary way to the other ; so that 

 the pair together resembles a coat of mail, or pair of stays ; and the entrances 

 of the cells look like the places for the arms to come out at." 



159- N. bursaria. — Cells compressed and attenuated. 



Shepherd's-purse Coralline, Ellis, Cor. 4. t. xxii. f. 8. — Sertularia bur. 



Linn. Syst. i. 1314 Cellularia bur. Pall. El. 65. — Dynamena bur. 



Lamour. Cor. Flex. 179. 



Height scarcely an inch, slightly branched dichotomously ; a mesial tube 

 extends throughout the branches, to which the cells are applied like wings ; 

 the cells themselves are inversely conical, with a thin edge ; the mouth is 

 tubular, produced, and arises near the axis. This species, though related to 

 the former in the position of the cells in pairs, is evidently the type of a new 

 genus, which may be termed Epistomia. 



Gen. LXI. EUCRATIA. — Branches consisting of a single 

 row of bent cells, the orifices of which have all one aspect. 



160. E. cornuta. — Branches subalternate, cells, nearly cylin- 

 drical, with a tubular orifice, above which is a long spinous 

 process. 



Goat's-horn Coralline, Ellis, Cor. 42. t. xxi. f. 10. — Sertularia corn. Linn. 

 Syst. i. 1316. — Cellularia falcata, Pall. El. 76. — E. corn. Lamour. Cor. 

 Flex. 149. — Adbering to fuci beyond low water-mark, not common. 



Height scarcely an inch, bending ; each cell forms a joint, gradually 

 curved, and becoming a little wider towards the top, where it is bent in- 

 wards to form an orifice ; and on the outer angle the base of the succeed- 

 ing cell takes its rise, between which and the orifice is the long bristle ; ova- 

 rium an enlarged, bladder-shaped cell. 



161. E. loricata. — Branched, subalternate, cells conical, with 



a raised orifice, beneath which is a spinous process. 



Bull's-horn Coralline, Ellis, Cor. 42. t. xxii. f. 9. — Sertularia lor. Linn. 

 Svst. i. 1316.— Cellularia chelata, Pall. El. 77--- E. chelata, Lamour. 

 149.
